Weight loss
This sign often indicates an advanced disease, and many cancer patients come to the doctor with this basic complaint. According to a 2006 study, there were 6000 to 7000 new cases of GBC reported annually in the United States. Out of them, 38% showed cachexia, which is a condition that causes extreme weight loss. It is a severe complication responsible for around 20 per cent of cancer deaths.
People with cachexia have a mayor unbalance of certain substances in their body that causes the loss of weight, even if they are eating properly. That means that in the presence of cachexia when a person does not feed properly just one day, he or she loses not only fat but muscle mass in a faster way than a healthy individual.
